Description

This 1876 copper medal at 58mm, cataloged as J-CM-11e, is the ungilt copper version of the U.S. Centennial commemorative medal at the 58mm size. The distinction between this copper version and the gilt copper variant (PCGS #515568) lies solely in the surface treatment — this piece retains its natural copper color rather than receiving gold plating. Copper medals develop distinctive patina over time that many collectors find attractive, ranging from warm brown to deep chocolate depending on environmental conditions and handling history. The J-CM-11e designation with 58mm diameter makes this a distinct size-and-metal variant within the comprehensive Centennial medal family. The 1876 Centennial medal in its numerous variants represents one of the most thoroughly documented medal families in American numismatics, with the Julian catalog tracking each combination of size, metal, and surface treatment separately for collectors pursuing completeness across the entire series.
